Yellow (A) Green (B) (+) Red Yellow (A) Green (B) ( ) White (+) Red EN 1. ELECTRICAL INSTALLATION MANUAL Installation works can be performed only by the specialists that have required qualification. During installation following requirements must be fulfilled. It is recommended to lay control cables separately from power cables in a distance no less than 20 cm. Connector connection is performed strictly according to numeration given in wiring diagram, or adequate markings (see wiring diagram). When disconnecting unit sections, do not pull by connecting wires and cables! Before starting any operations inside the unit, make sure that the unit is switched off and the power supply voltage is shut off. 1.1. Electric Power Supply Connection Air handling unit voltage is 230 V AC; 50 Hz, therefore it is necessary to install the socket with grounding of corresponding capacity (see wiring diagram). Electric power supply cable type is indicated in electric diagram. All units must be connected to the stationary installation by solid cable through 10A circuit breaker with 300 ma current leakage protection (type B or B+). Before connecting unit to the electrical power supply, it is necessary to check whether earthing has been installed properly in conformance with electric safety requirements. 1.2. Requirements for the installation of the control panel 1. The control console should be installed in a room where the following conditions are ensured: 1.1. ambient temperature: 0 ºC... 40 ºC; 1.2. relative humidity range: 20 %... 80 %; 1.3. protection against dripping of water (IP X0). 2. Control panel connection is provided through a hole in the back or bottom side. 3. The panel can be mounted on a flush mounting box or in any other place just screwing two holes on the fastening surface. 4. The control panel is connected to the controller box. The length of the cable for connecting the panel with the unit may not exceed 150 m. Do not use any other type or size screws but those that are packed together for control panel mounting.

Control panel connection and other cable thicknesses are specified in the wiring diagram! Remove protective screen tape, before mounting front cover on the control panel! 1.3. Kitchen Hood Connection Air handling units DOMEKT R 200 V have possibility of kitchen hood connection (in the functional diagram it is marked by KH). After fishing the cable through the rubber gasket, (located in the wall) it has to be connected to connection box J11 (1.3 Picture). Kitchen Hood Connection 1.3 Picture 1.4. External elements connection Depending on the model of a Domekt air handling unit and component parts, several additional cables can be led outside the unit for connecting external elements of the automatics: External control contacts. They are designed in all Domekt units. Outside the unit, a cable is led (see Picture 1.4 a), to which an external control device (switch, sensor, timer, button, etc.) can be connected, i. e. interconnection of normally open contacts (short circuit) will activate the OVR function. A more detailed description of connection possibilities is presented in Chapter 2.6. 1.4 a Picture External control box. If a water heater or a cooler is designed in the Domekt unit, then the unit is fitted with an external control box (see Picture 1.4 b), which is connected to the unit with a JW1 cable. Some elements specified below are connected to the contacts of the box. UAB KOMFOVENT we reserve the right to make changes without prior notice 5

EN The connection diagram of the external elements is presented on the internal side of the doors of the control box. Air damper actuator. Domekt air handling units can be ordered with the prepared connection for air damper actuators. In this case, an additional cable is led outside the unit. 230V AC supply and control voltage is provided for the connection of the actuator. Note: For units with water heater the connection of air damper actuators is designed from the external control box; therefore, connection should not be ordered additionally. For all units with a water heater, it is recommended to connect an actuator with a spring-return mechanism, i. e. in the case of loss of voltage, the actuator should close the air damper. Supply air temperature sensor. At units with an electrical heater, the sensor is factory-installed inside the unit. At units with a water heater or a cooler, the sensor is mounted outside; therefore, it is necessary to install it in the supply air duct downstream the water heater (cooler) section. The minimum distance from the air vent of the section to the sensor should be at least two diameters of the circular connection. Return water temperature sensor. It is connected to the external control box and is mounted on the return water pipe by screwing it into the designated vent. It is recommended to thermally insulate the sensor. Heating/cooling valve actuator. It is connected to the external control box. For hot/cold water mixing, it is provided connection for actuator with 24 V AC supply voltage and 0...10 V DC control signal. Circulation pump. It is connected to the external control box. 230 V AC supply voltage is provided. The pump is started up/shut down by the circuit breaker QF1. Feedback signal for heating or cooling. It is connected to the external control box. By default, the air handling unit is designed to operate with the water heater. However, the design of the control box provides for two terminals, by interconnecting (short-circuiting) of them the heater mode is reversed to the cooler mode. When the operation of the unit is switched over to the cooler mode, water freezing protection is deactivated. Therefore, when the unit operates in the cooling mode during the winter season, it is necessary to ensure that the water contained in the heater does not freeze. 1 external elements control box 2 return water temperature sensor 3 supply water temperature sensor 1.4 b Picture 6 UAB KOMFOVENT we reserve the right to make changes without prior notice

EN 2.4.3. Functions In this menu item, the user can activate and set additional unit functions: Setpoint sliding; OVR function. blank box: function is not activated; grey box: function is activated. Functions Setpoint sliding Override function 2.4.3.1. Setpoint sliding The setpoint can be shifted from -9 C to +9 C from the temperature set value at specifid by user time period. Event start and end time is set from 0:00 to 24:00 h. When setpoint sliding is active according to set time period, the setpoint sliding icon will be displayed in the main window (see chapter 2.2). Enable Setpoint -1.0 C Setpoint sliding Start time 11:00 Stop time 14:00 2.4.3.2. OVR function Air handling units have the OVR ( Override ) function. OVR function is intended for remote unit control by an additional external device. After the activation of this function the current mode of operation will be ignored and the unit will operate at a set intensity. The OVR function can be activated in two ways: 1. By the external control device. Connection is described in chapter 1.4. After interconnecting (short-circuiting) the FC contacts (see the electrical diagram), the unit will operate in the selected OVR mode and after disconnection it will return to the previous operation mode. 2. By control panel. In this case there is no need for additional connections to external control devices, the function is activated from the panel, and the unit will operate in the chosen OVR mode until the internal timer is active (from 1 to 90 minutes). When this function is active, the intensities of the supplied air and separately for the exhausted air fans can be adjusted from 20 to 100 %. When OVR function is activated, the modes buttons in main window are inactive. What is more, the corresponding icon appears in notification bar (see chapter 2.2). Applications of the OVR function: Maintenance of CO 2 quantity in room by adding an additional CO 2 sensor (with relay), the main user-set ventilation rate at higher CO 2 will be switched to the maximum or other intensity set until the room is ventilated, and then again will return to the previously mode. Maintaining relative humidity in the room after contacting the external relative humidity sensor (with relay), automatically switching to maximum or different set ventilation intensity the humidity level desired by the user will be maintained. Ventilation on demand when the motion sensor is connected to the control contacts, ventilation will be adjusted according to demand, i.e. if people are indoors, ventilation will be carried out according to the set OVR intensity and if there s nobody in the room the unit will operate according to the main user intensity, for example, the minimum.

Ventilation with additional air extraction connection of additional extracting device, for example, a kitchen hood or other extraction device without a separate fan, is intended, thus the air extraction is carried out by the unit itself. After the activation of the function the supply and exhaust air fans start operating at maximum intensity. Negative pressure compensation intended for systems where air extraction can be carried out in a separate air extraction fan. Thus, for the compensation of negative pressure in room, the OVR function can be activated by separate control contacts. After the activation of the function, only supply fan starts operating at maximum intensity and the exhaust air fan operates at minimum intensity or goes off. Note: To make this function work, namely to stop the exhaust air fan in the OVR mode, the jumper No 4 on the automation box should be ON (see chapter 2.5). 2.4.4. Settings This menu is for air handling unit and the user parameters setting. The user can switch the menu languages, change the screen saver, panel lock, touch sound, season, time and date. For the air handling unit operating in most economical mode, summer and winter seasons have been provided. Summer : heater operation is blocked but allowed cooler operation. Winter : cooler operation is unavailable but allowed heater operation. Time and date is required for air handling unit operation planning. 2.4.5.
